BRONANDER, OF MONTCLAIR, NEW JERSEY METHOD OF AND APPARATUS FOR FINTSHIN CLOTH Application filed September This invention relates to methods of finishing textile material or cloth and to machines for carrying out the method.

Textile material or cloth in passing through 6 the various dyeing and conditioning processes is scarred. marked or disfigured and requires finishing before it is suitable for the trade.

This invention has for its salient object to provide a method and apparatus for finishing cloth, the method being so carried out and the apparatus being so constructed and arranged that the cloth after treatment thereby will present a uniform, finished and polished appearance free from marks, blemishes or disfigurements. 7

Another object of the invention is to provide means for repeatedly treating the surface or surfaces of the material so as to effectively remove therefrom all marks, blemishes or disfigurements.

Another object of the invention is to provide means for spreading or stretching the material to its full width so that the web will be free from wrinkles or folds during its treatment.

Another object of the invention is to provide in a machine of the character described means for supplying treating liquid to the material to be treated as the material passes to the treating mechanism and to insure the application of the liquid to all parts of the material. I

Another object of the'invention is to provide in a machine of the character specified single means for spreading the web to its full width and for applying treating liquid to the web.

' Another object of the invention is to pro vide a novel and efiicientmethod of finishing and polishing cloth. 7

Furtherob1ects of the invention will appear from the following specification taken in 0on nection with the drawings, which form a part of this application, and in which Fig. 1 is a diagrammatic elevational view showing one form of apparatus constructed in accordance with the invention.

The invention briefly described comprises a plurality of cloth rubbing elements arranged to rub one or both surfaces of the cloth in opposite directions as the material passes through the machine. Means is also provided for stretching the material to its full width to prevent any longitudinal folds or wrinkles as the web passes to the rubbing devices, and this means also is constructed and arranged to finish and apply to the web of material treating liquid. In the particular form of the invention illustrated. the means last mentioned has a plurality of inclined or spirally arranged ribs extending laterally from the central portion thereof and arranged by their engagement with the material to spread the material laterally. Treating liquid is contained within the spreading device and has access-to the web through a plurality of apertures so arran ed that when the web is not progressing through the machine the apertures will be disposed in such a position that the treating liquid will not flow therethrough. Further details of the invention will appearfrom the following specification and claims.

In the embodiment of the invention illustrasted in Fig. 1, the cloth rubbing means comprises a plurality of devices indicated as A, B, C and D. Each of these devices consists of a relatively large roll 10 and a relative small'roll 11, around which extends an endless belt 12 formed of suitable flexible absorbent material such as felt.

Suitable driving means is provided for each of the rubbing devices, this means preferably being connected to the shaft of the relatively large roll 10 and the driving connections are so made to the respective rubbing devices that certain of the devices such as A and D will be rotated in one direction and others of the rubbing devices such as B and C will be rotated in the 0p osite direction. In this way the surface of t e cloth web 15 will be rubbed in opposite directions as it passes through the machine. I

After the cloth web has been acted on by the rubbing devices it can be led over an an idler roll 16 aridbe withdrawn iron: the machine by feed rolls 17.

Before the web of material passes to the rubbin devices it is led around a non-rotating to ow drum or roll 20. This roll is supported on trunnions 21: and 22 and as shown in Fig.4, 5 and 6, approximately one-half 23 (if 6 roll has formed on its outer surface a plurality of spiral ribs 24 which extend laterai'ly from the center of the roll. The other half 25 of the roll 20 has formed on its periplrml surfacels'piral ribs26 which also extend'iaterally from. the center of the roll but in the o posits direction from the ribs 24.

readily seen that when the materiai is drawn around or across the surface of the .roll'20 in the direction of the arrows 43% t e materialwill be spread laterally to its full width, thus removing any Wrinkles or 'n" itudinal folds. g

hollow shell or roll 20 also has for its on to provid treatin liquid to the maalas the material is rawn around the roll. A longitudinal opening is formed in the upper half of the roll'for receiving the treatin" li uid and the roll is preferably partially, led with absorbent material 31 such as cotton or waste. therein a through w wen One or both of the trunnions 21, 22 has secured thereto an arm 35 on which is adjustably mounted a weight 36 and stops 37 and are provided for limiting the movement of the arm 35. When the material is drawn around the roll the tension on the material and the friction between the ma.- terial and roll will cause the roll to be swung on its trunnions to the osition shown in Fig. 8 in which position it should be noted thatthe openings 32 are dis osed below the horizontal center plane of. e roll in posi biOlrtO permit the treating liquid to flow therethrough and rme ate tha'web of cloth, the cloth a been fed through the and no longer engages the roller 20, thefweight wfll swingtheroll in a clockwise fun teri The roll also has formed Iplurality of outlet openings 32 ich the liquid has access to the rti eywa wheum 35 will enga e the'step 38 aaditheopenin s 32 will ljiaflprosgioned above of the 0W position the W vices shown in rubbed alternately in opposite directions.

Furthermore, the belts in the devices E, G and I, will rub the under surfaces of the material and'the belts inthe devices F, H and J, will rub the upper surfaces of the material.

In this way both surfaces of the material will be treated.

In order to obtain the best results from the rubbing action of the belts 12, pressure rolls 18 may be mounted as shown in Fig. 2, to hold the material against the belts. Springs 19 press the rolls 18 toward the belts.

A roll 20 similar. to that already described is used in COIljlillCtlOIl with the rubbing deig. 2. A

In Fig. 3 rubbing devices K, L, M and N are shown and an idler roll 40 is interposed between each pair of rubbing devices. The material in this arrangement passes beneath the large rolls 10 of the rubbing devices and is rubbed on its upper surface only. Furthermore, the successive rubbingdevices are arranged to be driven in opposite directions so that the surface of the material Willbe rubbed alternately in opposite directions.

Fig. 7 illustrates another arrangement of the rubbing devices. In this form of the invention two devices, R and S, are shown and intermediate these devices there is arran ed an idler belt which passes around stationary idler rolls 46 and 47 and a vertically adjustable idler roll 48. The roll 48 has trunnions 49 carried by blocks 50 which are vertically adjustable by screws 51, the blocks being 'slidably mounted in vertical gulde-ways 52.

, .Fromthe foregoing description it will be seen that simple and practical means has been designed for treating one or both surfaces of a Web of textile material and furthermore that the material will be spread or stretched-to its full widthas it passes to the treatlng devices. By means of the repeated treatment or repeated rubbing of the Ina-- terial all marks, scars or blemishes will be effectively removed and the material will pass fromthe machine in perfect condition.

Although certain specific embodiments of the invention have been particularly shown and described, it will be understood that the invention is capable of nwdification and that changes in the construet'ionand in the arrangemen't of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
